There are many metal objects available to use for container planting, such as tubs, troughs, cans, buckets, cups, bowls, etc. While browsing through an antique mall, I found a metal basket that I thought was quite distinctive. The question I asked myself was, "What do I do with it?" My answer: "Plant succulents, of course!"

This is a great idea, and I have used metal baskets for my succulents as well. I didn't even think about using rust-proofing paint--thanks!
I like to use fabric mesh (nylon), such as bridal veil tulle to line my metal baskets. I also use small scraps of this to cover the hole in pottery so I can keep my soil in the pot and let the water pass through. I like your window screen idea too!!
